I knew it would be something simple, I was getting what seemed to be good pressure from the fuel pump!! when i check the injector outlets on the metering head i also had pressure!! when i checked at the injectors themselves i had no fuel thus the fuel pressure wasn't enough to open the injectors. i ran a hose direct from a fuel can to the fuel pump and hey presto she fired and ran as good as ever!! blew the tank out with an air line and she runs sweet. gonna remove the tank and check properly, the last thing i want is it to lean off at full boost and have a meltdown,

cheers for all your help guys sam
